Hi, I'm 18 years old and iv been experiencing weird changes with my body. I started birth control last year in 0ctober and my next appointment was on the 27th of December which I missed. The lady @ da clinic said if I miss my date for appointment and have unprotected sex I'd fall pregnant. I had unprotected sex with my bf and we got carried away on the 29th December. Now iv being having my periods from the 10th of January until today. Its scary because its not normal periods. Its very light but I'm having bad period pains, headaches, back pains, moody, feel like throwing up @ times,I can't eat and today I felt very dizzy but I thought it was cause of the heat. I don't know what it could be but I'm very scared to consult a doctor. Please help anyone. Thanks.
